Tooltips on Collapsed Left-Nav Icons

[Mike521w]

If the left nav is collapsed (by clicking the bars icon on the top/left) we can see just the icons for the various links (Catalog, Customers, etc). The Settings icon at the bottom has a tooltip on mouseover (via the `title` attribute), but the others don't. Can a tooltip be added to the others?

Yep, we'll file a bug to get the title text added to the collapsed menu.
